I recently acquired this set, my first 9v set. It’s a fairly basic set, but a good starting point into 9v.

Needed to make some track optimizations to cater for the smaller space, but wanting to maintain the same height for the upper level.

I recently obtained a couple of Power Functions trains second hand. I’m more newer to the hobby, so I’ve only had Powered Up before. I’ve got quite a few spare Powered Up motors and boxes laying around and wondering if when I rebuilt these older trains (which have been dismantled and washed) should I do it with their existing Power Functions components (which all work) or should I retrofit with Powered Up like the rest of my fleet?
